Application of the Central Encryption System in the Dynamic Secret Sharing Scheme (II)

Based on the simple introduction of the multi-teeth encryption-decryption algorithm (Shang, 2010, P.1500-1502.), a dynamic secret sharing scheme based on the multi-teeth central encryption system is proposed in this article. In this research, for any K system members B = {Bl, B2, — , Bk}, they respectively select thepositive integer in the set of XB = {xn,xa,---,xim} distributed randomly, and i = 1,2,—,k, and XBi is opened. By P , any l (or more) Bi could reconstruct the shared secret key, and k, l e N, l < k. The result indicates that the scheme proposed in this article has good characteristics of security and encryption
